How to Measure a Full-Face Gasket

Measuring a Full Face Gasket (also referred to as a flange gasket) can seem confusing.  It is critical to accurately measure 5 points on the Flange or Full Face Gasket to ensure your custom gasket is cut accurately and to your specifications.  The 5 critical measurement points are:

  • Inside Diameter (ID)
  • Outside Diameter (OD)
  • Number of Holes
  • Size of the Hole
  • Bolt Circle Diameter
